What if the dividing line is this simple?
As simple as Please and Thank You.
As in those who regularly say Please.
And those who graciously say Thank You.
As opposed to those who expect others to do for them or to respond to them or to get out of their way because they feel they are better or more important than those around them. Or those who think what they have to do or where they have to go is more pressing than what you have to do or where you have to go.

There is something about looking at another person and saying those words which acknowledges who the other is and what they are doing whether they are bagging your groceries or helping you meet the deadline for an important project. And saying those words reminds you that it is not just about you. Reminds you that your world is bigger and more complex and more inclusive and more dependent than we sometimes remember or acknowledge.
